ty of York and State of'lennsylvania; have invented 'certain nevv and .usefulflmprovenientsin Spring Supports, of'vvhich `the following'is a specification.V ,i

y Theinvention relates to improvements in spring supports for "securing side vsprings of an extension frame `for a motor veliic'le lto the, rear axle thereof Without materiallyfah tering said axle or its housing; j

It is 'an object of the invention toprovide a spring Support for application to the rear axle of an extension' lframe [secured .toza standard Fordtruck or carifor` connecting side springsito the rear axle in lieu ofthe usual .transverse springs of the standard Ford car vvitho'ut` altering ther axle` housing or partsA carried thereby. The inventionV further comprehends an improved attachment fo'r therear axle housing of a Ford when utilized in anfextension frame capable of adequatelyV supporting side springs,` and at the Sametime permitting vthe torque rod to be readily connected Without placing severe 'strains thereon.

. lVith the foregoing conception in mind, the invention' primarily resides in mounting side springs on plates pivoted to said spring supports so that the'torque rod can be freely elevated to a position to be connected with the extension vsha-ft casingl" In the accompanyingPV 4drawings We have "shown a preferred embodiment of our invention, in which:

Figure 1 is a plan View of a motor vehicle chassis with an extensionframe applied thereto and With side springs secured lto the extension frame and 4to the rear axle;

Fig; 2 is a side elevation thereof: Fig.-3 .is an enlarged section on the line 84.3 ofFigJl..` a l Fig. L.tis a; horizontal section on the yline Ll--lof Fig.- 3, i. .i

Fig..5 .is avertical 'sectionon the'line 1Eig. Gis an enlarged section on line l6-.6 orma-2. Y- y f .F ig.- 7; is asimilar view on'the line' 7-7 ofFig.2.

f :Referring now more particularly to drawings wherein .like reference characters Vindicate corresponding 'parts5the numeral 1 designates the usual Ford frame or chassis to vvhichthe extension frame 2; is applied; This frame isunited to the standard chassis lin any Well known manner?. Thefrearl end of the frame 2 is connected vvvith the rear axle housing 3, which housingcontains the usual, drivingy axle,yk dierential mechanism,Y etc., and is' in fact the standard "axle and housing usedy in the .Ford truck. On each side of the .extension `frame side springs 4 are provided, these springs being secured at their Aforward ends to vthe permanent spring hangers 5 'attached tothe vextension frameyvvhile the rear ends .of the springs are secured to the frame bya pivoted shacklev 6 calredv by bracket 7; l' The presentcinvent-ion comprehends improved means for securing'said side'springs 4 to 'the rearv axle of the vehicle. It Willbe appreciated that the rear axle utilized with the 'extension frame is the standard lFord,

ly ,and'outW-ardly from the support 7 'It Willkb appreciated that perch support axle yhousing near each side thereof as this structurel is lutilized in the .Ford- .carfor supportingthe transverse springs which are not employed in the present'extension frame. In lieu of these springs the4 present invencasting and spring perch is disposed on the 1 tioncontemplatesthe use of the. side `springs 4f which are -co'linectedto the axle housing inamanner to/be nowdescribed.v

'. A spring` support is disposeduateach side of f the.. housing and inasmuch as .each supportis of lthe same identicall construction a. descrip; tionof one will `suie,ef 'f,or both. lThis sup.;- port .has .a verticali-arm: 10 of substantial :U- sha-ped .cross-section and., so .clonstructedas to .span` the upper .end olf .its perch 8; The

separated portions of 'the vertical-arm `are i provided with alined apertures adapted to receive a perch support bushing 12 passing therethrough and through the usual opening found in the spring perch. A perch pin 13 is preferably passed through said bushing and secured in position by washers or the like. The spring support is also provided with a substantially horizontal body section 14E preferably integral with the vertical arm thereof and adapted to extend substantially parallel with the axle housing. The base of the body is provided with a pocket 15 of substantial depth. The side walls of the pocket have therein a pair of alined portions 17 receiving the pivot pin 18 for a purpose which will now appear.

To provide a pivot seat or connection for each side spring 4 the base of each support receives in the pocket therein a spring pad or plate 19 having a centrally depending part 20 adapted to fit within the pocket 15 and centrally apertured to receive the supporting pin 18 passing through the openings in the walls of the pocket. The pocket in the base of the support is of such an area as to provide a clearance sufficient to permit a rocking movement of the spring pad or plate on the rigidly mounted bracket 10.

To hold each bracket in a rigid position on the axle housing and to support the major partof the loa-d on this housing, the base of the bracket is formed with a downwardly-extending portion 20 having a yoke 21 encircling the upper part of the axle housing. A fastening yoke 22 is also placed around the lower part of the housing and these yokes are united by' fastening bolts 23 disposed on both sides thereof. When the bolts are tightened the bracket is rmly drawn down on the axle housing and is incapable of any movement relative thereto. The pivotal connect-ion between the vertical arm 10 of the bracket and the spring perch permits the base of the bracket to be initially adjusted with reference to the axle housing so' that it may be properly attached even though the housing or the perch may not be free from defects or irregularities in contour.

It will be understood that the spring pad 2O mounted on the base of each bracket is free to pivot on its supporting pin 18. The axle housing' is, therefore, capable of a certain rotary movement relative to the springs and the frame. Each side spring is attached to its pad by means of a center bolt 2a passing through an opening in one of the spring pads and through the spring leaves. U- shaped fastening bolts 26 are also preferably employed for securing a spring to its pad at each side thereof. The pivotal movement of the axle or the pivotal movement'of the springs is highly benecial as it permits the torque shaft 28 to be freely elevated to .a position where .it canbesecured tothe casing of an extension drive shaft during the assembly of the frame. In the past where the springs are rigidly mounted upon the axle housing if the torque shaft is slightly sprung it is exceedingly diflicult to connect the same at its forward end. In fact, it has often been necessary to `utilize great pressure in forcing this; shaft to a point where a connection can be made. Such pressure is not necessary when the springs are pivotally connected in the manner described.

Having thus described the invention, what we claim is:

1.' The combination with a vehicle chassis having a rear axle and a housing therefor, of a spring perch support and a spring perch on said housing, a bracket having a base and an arm extending therefrom, means for securing said arm to said spring perch, means for securing said base to the axle on said base and Vdisposed below said spring perch, and a side spring secured to said pivotally mounted spring plate.

2. The combination with an automobile chassis including side frames, a rear axle a-nd a housing therefor, of a supporting element carried by said rear axle and disposed above the same, a spring supporting bracket having a substantially horizontal base and a vertical extension,.means for attaching said extension to said support carried by the axle, a spring plate pivotally mounted on said base below the point of attachment between said arm and said support, means for clamping said base to the axle housing, and a spring rigidly connected to said plate.

3. The combination with an automobile chassis, including side frames and a rear axle, a perch support carried by said axle, a spring perch connected with said support and extending therefrom, a spring bracket, said bracket being provided with a vertical arm pivoted to said spring perch, the bracket having a body portion disposed adjacent the axle housing, a pivoted spring plate, means carried by said horizontal body of said bracket for pivotally mounting said plate below the pivotal connection between said arm and said spring perch, a spring connected with said pivoted plate, Vand means for clamping said bracket to the axle houslng.

4. The combination with the rearaxle of an automobile, a perch support, a spring perch projecting therefrom, a spring supporting bracket having a horizontal body portion disposedl adjacent the axle of the housing and connected therewith, and a vertical arm extending substantially above the horizontal body of the bracket, means for connecting said vertical arm to the spring perch, a spring plate pivotally mounted on said body of the bracket and lying below Vthe point of connection between said upstanding housing, a spring plate pivotally mounted part' thereof and said spring perch, and means for securing a spring to said pivotally mounted spring plate.

5. The combination With the rear axle of an automobile having an axle housing, a perch support, a spring perch projecting therefrom, a bracket having an arm, means for connectinzgI said arm to said spring perch, said bracket being provided With a 10 horizontal body portion. disposed adjacent the axle housing, a pocket Within said body portion, a spring plate, means for pivotally mounting said spring plate in said pocket,
